read - function
(read reader)
(read opts reader)
(read reader eof-error? eof opts)
Reads the first object from an cljs.tools.reader.reader-types/IPushbackReader.
Returns the object read. If EOF, throws if eof-error? is true otherwise returns eof.
If no reader is provided, *in* will be used.

Reads data in the edn format (subset of Clojure data):

cljs.tools.reader.edn/read doesn't depend on dynamic Vars, all configuration
is done by passing an opt map.

opts is a map that can include the following keys:
:eof - value to return on end-of-file. When not supplied, eof throws an exception.
:readers  - a map of tag symbols to data-reader functions to be considered before default-data-readers.
           When not supplied, only the default-data-readers will be used.
:default - A function of two args, that will, if present and no reader is found for a tag,
           be called with the tag and the value.

read-string - function
(read-string s)
(read-string opts s)
Reads one object from the string s.
Returns nil when s is nil or empty.
